Each Impactor Box System (IBS) on COLLIDE is held together
by 83 screws. This makes for a total of 498 screws just for the six
IBS's on COLLIDE.

Okay, maybe that one isn't that fun. But
check here for new trivia and minutiae related to COLLIDE as we begin final
assembly and integration.

I think it's pretty fun that Lance's Support Structure
didn't fit into the GAS container NASA shipped us. Of course,
Lance doesn't think it's that fun, and neither would I if we had waited
until the experiment had been fully assembled before checking the fit.

Even though COLLIDE is basically a mechanical experiment,
we still have 130 major electrical lines and will probably have close to
1000 feet of wiring when completed.

The strongest spring on COLLIDE for launching its
projectiles in microgravity environment of Earth orbit is only strong enough
to lift our teflon impactors about 5 millimeters in the one Earth gravity
environment of the laboratory. In space, this should launch the projectile
at a speed of 1 meter per second. In contrast, the slowest projectile
is designed to travel at a sloth-like 1 centimeter per second.
